Update biology/seaview to the latest version.
Unbreak (checksum mismatch problem due to upstream distfile name
being constant through version updates)
CC goes to Kris, the pointy hat owner because of:
[ports-i386@FreeBSD.org: seaview-2004.12.16 failed on i386 6]
I'll look at this.
Committed with (approved) modifications. Thanks!
